RE: [PipingDesign] Mitre bends

See ASME B31.3 for guidance.... its an internationally recognized code for
Process Piping....

I will also say get a good fabricator this has all sorts of bad possibilties
associated with it... and finally don't forget stress analysis and its impacts
on these elbows....

Hi friends,

I would like to know your comments on using Miter / Mitre bends in piping in
different conditions like

Limitation, if any, pressure and temperature wise

Limitation, if any, service wise,

limitation, if any, size wise

Any thumb rule.

At present, we need to fabricate two new pipelines on urgent basis. The
first one will be within the plant, operating at 12 kg/cm2 pressure, at 200
C temp. The other one is in the offsite (connected to to storage tanks).

Due to non-availability of pipe fittings, we may need to use Miter bends.
However, there is some opposition regarding the use of same. Both cases,
service fluid is hydrocarbon (SR naphtha to be precise).

Your comments and any guidelines to relevant codes will be highly
appreciated.
